The muscles which raise the scapula are the upper fibers of the Trapezius, the Levator scapulæ, and the Rhomboidei; those which depress it are the lower fibers of the Trapezius, the Pectoralis minor, and, through the elavicle, the Subclavius.

There are often heat, pain, and swelling in the muscular mass at the elbow, though at times a hollow, or depression, may be observed near the posterior border of the scapula, which is probably the seat of injury.
